This workshop explores the traditional process of assembling a herbarium specimen, inspired by Jean-Jacques Rousseau’s collections. Participants learn scientific techniques for pressing and mounting dried plants on old paper, practice botanical labelling and nomenclature, and select specimens to create a personal herbarium sheet. The session examines preservation methods, identification principles and the historical context of Rousseau’s approach, combining practical skills with scientific insight to produce a lasting botanical object.

This interactive memory challenge invites participants to test their memory while exploring practical ways to preserve biodiversity based on Geneva’s municipal strategy. Players match “before-and-after” images that illustrate individual and institutional actions, and each correct pair reveals concise information explaining the measure. The activity examines themes such as habitat restoration, species-friendly practices, urban greening and policy responses, helping participants understand the impact and rationale behind everyday and organisational conservation choices.
